66 Dart GT HT Whatsitgonnabe?

What kind of compressor and part number is it. I may have at least 1 rod you can have if the PN is the same or similar enough that it will work. Had 1 rod lock up. Other one is good. I bought a new compressor pump. Was saving this bad one for parts. Get me a pump part number, and a rod part number.
That would be just too much luck.

This is an ABAC B3700, a 4hp unit. Big end ID is 37 mm, little end 15. C-C roughly 105 mm. The number 3610190 is cast into it.

Here's a pic of the rod:
